Slaty Elaenia
Elaenia strepera
Highly migratory flycatcher; it nests from about September through March along the east slope of the Andes in Bolivia and northwestern Argentina, then disperses as far as northern South America. It is mostly gray, with a pale belly, faint wingbars, and a broken eyering. Bill is stubby and yellow at the base. Male has a white crown patch that is usually hidden; females and immatures are tinged olive. Inhabits humid forest, and very inconspicuous when not singing. Typical song is an accelerating, toneless rasp, and it remains almost totally silent outside of its breeding range.

Straneck's Tyrannulet
Serpophaga griseicapilla
Small flycatcher with a gray head, an olive-brown back, a whitish throat, and a yellow belly. Note the white eyebrow and broken eye-ring. Occurs in woodland and scrub; migrates to the northeast during the austral winter. The song is a single note followed by a trill: “twie tirrrrrrrrrrrrrrrrrr.” The similar White-crested Tyrannulet has a different song and is also slightly larger, with a white crown patch that is often concealed.

Everett's White-eye
Zosterops everetti
Typical white-eye; greenish above and grayish below with broad white spectacles around the eyes. Darker gray belly and more extensive yellow on the belly than in the marginally smaller Oriental White-eye. Inhabits foothill and montane forest edges, gardens, and secondary growth, occasionally around human habitation. Gregarious, often foraging in large flocks, both single-species and mixed. Moves through the upper levels of forest, though can descend into middle and lower levels in edge. Song consists of repetitive twittering; also gives whistles and buzzy notes while in flight and when foraging.

Little Sparrowhawk
Tachyspiza minulla
A tiny, secretive and inconspicuous hawk that flies quickly and nimbly within woodland thickets and forest while hunting small birds, other vertebrates, and insects. It has a very distinctive white rump and two pale spots on the upper tail. Call is a distinctive high-pitched bisyllabic, down-and-upslurred “chy-lip”. Similarly-plumaged African Goshawk is much larger; Red-thighed Sparrowhawk is similar in size but prefers dense rainforest, is more rufous below, and generally lacks barring on the underside.
